the full answer...

If any type of bird is nesting in a tree or hedge then it is legally protected, so long as the nest is in use. This may prohibit certain types of tree pruning or removal until the nesting season is over. Removing dense hedges or substantially reducing them would be illegal, but annual trimming may be acceptable. Birds commonly nest between March and the end of July. Take A Bough Tree Care’s London tree surgeons will be able to advise you of the best time to undertake such work.

Many kinds of bats use trees to roost in, either for long or short periods of time. Bats are all protected and when carrying out works to a tree that is likely to contain bats, it may be necessary to survey it first. Take A Bough Tree Care have trained staff that can do this for you. If tree work must be carried out in an emergency, then this may override protected species and we can advise you where required.
